The elevation of the city is between -15 and -16
Step-by-step explanation:
The Earth surface is highly uneven. Hence for relative comparison, scientist over the world assume the sea level as the reference point (meaning that sea level is considered to be at 0 elevation and all other elevations and depths are calculated regarding the sea level)
As given in the question city’s elevation is 15.3 feet below sea level. Hence the city is below the sea level by 15.3 feet
On the mathematical scale below 0 would mean the number system is negative. Similarly, the city is located at -15.3 feet when compared to sea level which is at 0 feet.
Hence -15.3 would lie between -15 and -16
